I have looked at several and this is the one!! Lol. It has that extra slot to hold your phone. Plus, it doesn't just have the wine glass slot -- it also comes with a circular area that will hold a coffee cup or regular cup. Many of them had that wine glass slot but no regular cup holder!
I have these French bee glasses that hold water or iced tea but look like wine glasses because of the stem. I was afraid the bottom might be too thick to fit into that slot.
Oh, it's adjustable to fit narrow or wide tubs, V.
